DETAILED DESCRIPTION OF INVENTION

[0019] The present invention is further explained below along with the accompanying drawings. The drawings are all simplified schematic diagrams which only illustrates the basic structure of the present invention, as such only the components material to the present invention are shown.

[0020] A smart pressure-sensitive measuring device for femoral tumor removal is shown in FIGS. 1-3. The device comprises a rectangularly structured alignment plate 1, a measuring ruler 2 and a measuring angle adjustment mechanism 3. An inverted T-shaped rail 11 having a single opening is disposed on the alignment plate, a slide rail 15 connected to the inverted T-shaped rail 11 is disposed at a side of the alignment plate 1. A magnetic plate 16 is mounted at a bottom of the inverted T-shaped rail 11.

The pressed location is set as 0-reading at the pressure-sensitive display 22, and displays a second reading 21 that uses the 0-reading as the base and increases towards two sides in scale. The second reading 21 is two rows of readings symmetrically disposed relative to the center axis of the measuring ruler 2. A USB charging port 27 electrically connected to the display control circuit board 24 is disposed on the measuring ruler body 21, a silicone plug is disposed on the USB charging port 27 for preventing water and dust.

[0025] The smart pressure-sensitive measuring device for distal femoral tumor removal of the present invention comprises an alignment plate, a measuring ruler and a measuring angle adjustment mechanism. The measuring ruler and the alignment plate is connected to each other through the measuring angle adjustment mechanism, can adjust the angle depending on the circumstances of each patient. In use, the right side wall of the alignment plate is pushed towards the two circular contact surface of the femoral medial condyle and lateral condyle, the measuring ruler can slide freely inside the inverted T-shaped rail to adjust the position of the measuring ruler, being convenient to use and prevent measurement deviation of the length of distal end of the femur caused by the Q-angle of the knee. The pressure-sensitive display disposed on the measuring ruler uses the pressured location as 0-reading, and displays the second reading that uses the 0-reading as the base and increases towards the two sides in scale, facilitating the marking for surgeries, increasing the level of automation of the device. The adapted battery is a rechargeable battery, therefore having a longer operating life. The magnetic plate at the bottom of the inverted T-shaped rail of the alignment plate produces damping to the slider, making accurate positioning of the measuring ruler easier.
